As the land of Canaan had one year of release in seven, so has the world one millennium of release in seven thousand years; for it is said (Isa. ii. 17), "And the Lord alone will be exalted in that day;" and again (Ps. xcii. 1), "A psalm or song for the Sabbath day," which means a long Sabbatic period, and again (Ps. xc. 4), "For a thousand years in Thy sight are but as the day of yesterday."
